Set up sound selections, set operation CVs and calibrate Dynamic Digital Exhaust

Tsunami2 Sound Selection

Diesel: • Select Air horn - CV 120

• Select Bell - CV 122• (0-49, +128 to enable Grade-Crossing Logic bell)

• Select Prime Mover - CV 123• Pitch shift in CV 223 (V1.2)

• Select Air Compressor - CV 124

• Select air dryer or poppet valve CV 125 (V1.2)

• Select Coupler - CV 126

CV 112- Sound Configuration 1

• Used to Select Sound Setup• E-Stop Prime mover reaction, idle or shutdown

• Low-Pressure Alarm Bell Enable

• Gen Select• Steam generator

• Aux diesel HEP

• True Idle Enable

CV 114- Engine Exhaust Control

• Used to control the prime mover sound effects• Auto notching rate can be changed to allow for more or less speed steps per

prime mover notch.• It is recommended to set the auto notch rate to 15 for a smoother response of the

Dynamic Digital Exhaust.

• If auto notching rate is set to 0, manual notching is enabled and the RPM+/RPM- (default F5 & F6 keys) are used to control prime mover notch

• Prime Mover Interlock bit

• Auto-Start bit

• Dynamic Brake override bits• 4 modes of operation: no change to PM, EMD (idle), ALCO (N8), & SP (N4)

Calibrate Dynamic Digital Exhaust

• Run the model for at least 2 minutes before starting the process

• Set CV 32 = 2 to access the second index (location of the DDE CVs)

• On a flat, level track without any load behind the loco, perform the following steps:• With model at speed step 1, set CV 2.503 = 255

• Increase to speed step 25-30 (of 128)

• When model reaches that speed, set CV 2.504 = 255

• Adjust CV 2.512 to your liking to further tune the prime mover’s response to changes in load or grade. Set CV 2.512 = 32

RPM+ & RPM-

• F5 (RPM+) is used to start the prime mover and increase the notch

• F6 (RPM-) is used to shut down the prime mover or decrease the notch

• Can be used with auto notching enabled and DDE to adjust the notch up or down as desired

• F10 Straight to Notch 8

• F19 Straight to Idle

• NEVER Lose control of loco speed!

Outputs

Diesel Lights

• F0 turns on the headlight/back-up light.

• F24-27 are used to turn on the FX3-FX6 outputs.

• The default “Diesel Light” Hyperlight effect mimics the short duration necessary for the lamp to reach full brightness.

• Tsunami2 decoders feature over 25 selectable Hyperlight lighting effects including: Ditch lights, strobe light, Gyralight, Stratolight, rotary beacon, Mars light and many others.

Independent and Train Brakes• F11 activates the air brake features built into the decoder

• Tsunami2 supports both air brake systems found on a diesel locomotive

• Independent (Locomotive Brake) when function 12 is off

• Train (Automatic Brake) when function 12 is on

Train (Automatic) Brake

Independent (Locomotive) Brake

Independent & Train Brakes

• Independent brakes play sound of engine brake squeal

• Toggle between braking types using F12

• Turning on F12 will “charge the train line” causing the air compressor to turn on and the prime mover to elevate to Notch 3.

• Train brakes play the sound of an air reduction known as an application or set

• Both play unique sounds of a release when function 11 is turned off

• Brakes may be configured to affect speed of the train or simply play the sound effects

Relate to the Prototype: Use of Air Brakes

• Independent Brakes (Locomotive)• On the prototype, this is a “straight air” system. Positive pressure is used to

apply the brakes.

• More modern systems can be “MU-ed” together to allow for control of brakes on a multiple unit consist of diesel locomotives.

• Used when the brake pipe connection is not present to the rest of the train (i.e. switching, light engine moves, and to adjust slack)

• In your models: • Typically give stronger braking value in model to properly simulate this brake

• Sound effect will squeal when applied and play a bail off when released

• Should be first sound you hear released before you move your model

Relate to the Prototype: Use of Air Brakes

• Automatic Brakes (Train)• On the prototype, this is an “equalized” system. Positive air pressure is used

to hold the brakes off.

• Used when the brake pipe connection is coupled between the engine(s) and all the rest of the cars.

• Typically would be much slower and more gradual reduction in train speed than the independent brake

• In your models:• Sound will play the noise of air reduction when function key is turned on and a release

sound when the function key is off.

• Brake squeal would then come from the Tsunami SoundCar

Dynamic Brakes

• Dynamic braking is used to control the speed of trains when descending long grades.

• The traction motors are changed to generators which impart resistive force on the wheels, slowing the train.

• The electricity generated during the braking process is dissipated though large grids on the locomotive roof cooled by multiple fans.

• Tsunami2 decoders feature a multi stage dynamic braking effect with an additional brake rate option to add more realism to operations.

Dynamic Brakes

• When cresting a grade on your model railroad, press the F4 key once to move into the “low” dynamic brake notch. This will play the dynamic brake sound effect and maintain train speed.

• As more braking effort is required, press the F4 key again to enable the braking rate as set in CV 116 and the “high” dynamic brake notch.

• Like the prototype, Tsunami2 dynamic brake only slow down the train and will not stop the model. As the model slows to speed step 8 (of 128) you will hear the dynamic brake sound effect return to the “low” notch and speed will be held.

• If dynamic braking effort is no longer required, press the F4 key a fourth time to turn off the dynamic brakes.

Passenger Operation• HEP is used to provide power to passenger cars for lighting, HVAC, and

other appliances.• F16 starts the warning bell then raises the prime mover to N8 (EMD, ALCO,

Baldwin & Others) or N6 (GE).• The diesel engine turns a HEP generator at a constant RPM hence the need

to increase engine RPMs.• F20 Enables Steam Generator or Aux HEP ‘Pup Motor’

General Service

• Fireman Ed! Performs various tasks around the loco

• F17- Fueling the loco

• F18 Triggers general service• Cab door

• Wrenches

• Pneumatic Lubricators

• AC unit, cab chatter, toilet flush and more!

Automatic Sound Effects

• Air compressor

• Radiator fans• Operates based on loco use

• Poppet valve or air drier• CV 200 used to control the rate

• “Clickety-Clack”• Rail joints sound effect

Relate to the prototype: Dynamic Digital Exhaust

• Starting & Running on flat track examples

• Engine demand is based on tonnage. Therefore, it may be in run 8 and loud, but only going 15-20mph when hooked to a long cut of cars

• Engine maybe going 70 mph with light passenger train and bouncing between run 2 and 3 depending on slight variations in grade

How to Start a Diesel Locomotive

• Turn on Headlight (F0)

• Blow proper whistle (horn) signal (F2/F3)

• Throw Reverser forward (Direction/F5/F6)

• Turn on bell (F1)

• Open sander valve (F21)

• Gently open throttle to pull out coupler slack (Throttle Knob to SS1)

• Release independent/train brake (F11)

• Adjust throttle to pull slack based on tonnage (DDE, F5/F6)

• Close Sander valve (F21)

• Open throttle to get moving up to speed (Throttle Knob)

How to Stop a Diesel Locomotive

• Blow proper whistle (horn) signal (F2/F3)

• Reduce throttle (Throttle Knob to SS1)

• Turn on bell (F1)

• Open sander valve (F21)

• Gently apply (feather) brakes on and off to stop (F11)

• Close Sander valve (F21)

• Couple to the train (F13)

Relate to the prototype:

• Operational Tips

• Add some momentum for more realistic acceleration and deceleration

• When tied onto train, activate F12 to ‘charge the trainline’ and set proper sounds for handling a train• When coupled with SoundCar, creates a great operational scenario!

• Adding in sound operation helps slow down the op session, do more in less space

• Set F# keys to match you and your operator’s tastes, or to match DCC throttles in use for best enjoyment and ease of operation

Conclusion

• Understanding diesel locos is key to Tsunami2 development

• Running trains can be more than just adjusting the throttle knob

• Using the loco(s) more like the prototype makes operating sessions more interactive and more fun!
